Comparability
In 1996, MULTILOCRD only includes persons aged 16 and older with a current main job who are wage earners (e.g., not self-employed), who are eligible in rounds 1 and 2 of data collection; in subsequent years, RUSIZERD is available for all persons aged 16 and older who have a current main job and are wage earners. Otherwise, this variable is completely comparable across time.
